1970 Map of Breckenridge

About this map

Breckenridge sits at the heart of this high-altitude landscape, captured in 1970 as the area transitioned from its deep mining roots into a premier alpine destination. The map details the nascent Sawmill Ski Area on the slopes below the Tenmile Range, marking a pivotal shift in land use. Meanwhile, the legacy of the late 19th-century boom is still plainly visible through an extensive network of gulches and lodes, including the Wellington Mine in French Gulch and the Briar Rose Mine on the shoulder of Peak 10. Hydrological engineering for the growing Front Range is evidenced by the Blue River Diversion Project, which includes a tunnel system beneath the Continental Divide. From the peaks of Quandary Peak and Pacific Peak to the waters of Goose Pasture Tarn, the map documents a terrain defined by rugged relief and resource management.
